Distributed Data Movers (DDM)

In most software archive architectures there often exists some sort of bottleneck when moving data (I/O) to and from the “archive.” These architectures are problematic, causing unknown server sizing as well as limitations to load level as performance needs grow. In a StorNext-based architecture, the actual data movement is handled by a Distributed Data Mover (DDM), which acts as the conduit for passing data to and from primary storage to the storage tiers. As the archive becomes more active, you can simply add more DDMs to scale the system performance. These movers enable reads and writes of file copies for data preservation and retrieval while still providing fast access to data via the copy on primary disk.
